Io Drawing.

To all whom it may concern:

-Be it known that I, James L. DILLON, a citizen of the United States, residing at Leavenworth, 'in the county of Leavenworth and State of Kansas, have invented certain new and useful Bearing Com ositions, of which the following is a speci cation.

This invention provides a composition for use as bearings for working parts of machinery, for shafting, for journals generally, and in other places where lubricant ordinarily is required. Bearings formed of the composition do not require oil, grease, graphite, or other lubricant to diminish friction and prevent undue wear of working arts.

T e composition includes wood ul powdered or comminuted asbes os, powdered or comminu'ted 'ra hile, Portland or other h 'draulic oemen pow (21mmminut mica su iur and animal blood.

Preferably ihe pu p of har we is use in the composition, and it is introduced during mixing in any form that will permit it to be rendered plastic by moisture. The asbestos is used 1n the form of a powder or in comparatively small particles or strands. The graphite preferably is used in the form' of a fine powder. The cement is used in its commercial form of a fine powder. The mica is used in the form of a. powder or comparatively small particles The sulphur is used in any of the natural forms that are subject to bein rendered plastic by moisture. The blood is used in liquid form, and the blood of swine or other animals may be employed;

Ingredients of the composition, together with the animal blood ingredient in quantity suflicient to render the mixture plastic to, or about to, the consistency of ordinary bread dough, are mixed in any suitable manner in substantially the following proportions: Wood-pp] 10 parts: asbestos 10 parts;' g 1 ap 1t e, 5 parts; cemm b pdrts;

giica, 2% parts; and sulphur I pai t. "The composition'ilihs ormed, and while Application Med December 18, 1922. lerhl llo. @7355. a, S 2 L/ still in a plastic condition, may be molded in any suitable manner into the 'articular forms required, and after the mo? cles harden or set they may beused as bearings any places where friction between working parts occurs.

It has been found in practice that bearings of this composition, or having this composition thereon, do not require addition of lubricant thereto to diminish friction and prevent undue wear ofparts moving in contact therewith.

Having thus described my invention, what 00 I claim as new, and desire to secure by Letters Patent, is-

1. A material for bearings that includes wood-pulp, asbestos, gra hite, hydraulic cement, mica, sulphur, an animal blood.

,2. Material for bearings formed b mixmg wood pulp, asbestos, graphite, hy aulic cement, mica, sulphur, and sufiicient liquid to render the mixture plastic during min-- ing of the in redients. 3. Materia for bearings formed by mixmg wood pulp, asbestos, graphite, hydraulic cement, mica, sul hur, and sufiicient animal blood to render t e mixture plastic during nuxin of the ingredients.

4. l\ aterial for bearings formed by mixing the -iollowing ingredients in substantially the proportions stated; namely: wood pulp, 10 parts; asbestos, 10 parts; graphite,

5 parts; hydraulic cement, 5 parts; mica, 30

2-1; parts, sulphur, 1 part; and sufficient liquidto render the mixture plastic during mixnig of the ingredients. J

5. aterial for bearings formed by mixin the following tl'fily the proportionsstated; namely: wood pulp, 10 parts; asbestos, 10 parts; gra hits, 5 parts; hydraulic cement, 5 parts; ice, 2% parts, sulphur, 1 part; and suflicient'anima blood to render the mixture in mixing of the ingredients.

n testimony whereof I atfix my signature.
